Static Electricity Review Quiz

What is static electricity?

• The build-up of electric charge on the surface of objects.

• The interaction of magnetic fields with electrically charged objects

• The absence of electric charge on the surface of objects

• The flow of electric charge through a conductor

How is static electricity different from current electricity?

• Static electricity is only found in nature, while current electricity is man-made.

• Static electricity is the flow of electric charge through a conductor, while current electricity is the build-up of electric charge on the surface of objects.

• Static electricity is the build-up of electric charge on the surface of objects, while current electricity is the flow of electric charge through a conductor.

• Static electricity and current electricity are the same thing.

What are some examples of static electricity in everyday life?

• Touching a metal doorknob after walking on grass

• Using a hairdryer on wet hair

• Rubbing a balloon on hair, walking on carpet and getting a shock, clothes sticking together after being in the dryer

• Sitting in a car and feeling a shock when touching the door handle

What causes static electricity to build up?

• Presence of water on the surface of an object

• Imbalance of electric charges on the surface of an object

• Friction between two non-conductive materials

• Exposure to direct sunlight

How can static electricity be discharged?

• Grounding the object or using a discharge device

• Heating the object in a microwave

• Exposing the object to water

• Rubbing the object with a cloth

What is the concept of positive and negative charges in static electricity?

• Equal distribution of protons and neutrons

• Imbalance of protons between two objects

• Imbalance of electrons between two objects

• Friction between two objects

What is an insulator and how does it relate to static electricity?

• An insulator prevents the flow of electrons and helps in the buildup of static charge.

• An insulator has no effect on the flow of electrons and static charge.

• An insulator allows the flow of electrons and helps in the buildup of static charge.

• An insulator attracts electrons and helps in the dispersion of static charge.

What are some safety precautions to take around static electricity?

• Jumping up and down to release static electricity

• Grounding yourself before touching sensitive electronic equipment, using anti-static mats or wrist straps, and avoiding wearing clothing that generates static electricity.

• Rubbing balloons on your hair to increase static electricity

• Using a metal ladder during a thunderstorm to discharge static electricity

What are some ways to demonstrate static electricity in a classroom?

• Using a water hose

• Swinging a pendulum

• Using a balloon to create static charge, rubbing a comb on a wool cloth, or using a Van de Graaff generator

• Baking a cake

How does static electricity affect objects and materials around us?

• Static electricity can cause objects to attract or repel each other, and can also cause materials to stick together or repel each other.

• Static electricity has no effect on objects and materials

• Static electricity can cause objects to explode

• Static electricity can make objects invisible
